Which risk increases when a prolonged drought causes stomatal closure in plants?

💡 Explanation

When stomata close during drought conditions, carbon dioxide uptake decreases, and oxygen accumulates within the leaf because the stomata regulate gas exchange. Therefore photorespiration increases because Rubisco binds to oxygen instead of carbon dioxide, rather than nitrogen fixation, excessive growth, or accelerated nutrient uptake which require different conditions such as adequate water or modified transpiration.
